A flight test challenge - Aeroassist for reuseable, space-based transportation

Abstract

Attention is given to the challenges addressed by NASA in the development of reusable, space-based transportation systems which take advantage of aerobraking to achieve greater performance and overall efficiency. Aerobraking environmental factors associated with achieving higher energy reusable systems are outlined and the need for a coupled utilization of ground test capabilities and computational fluid dynamics (CFD) is demonstrated. It is concluded that the certification of CFD capability to provide the aerodynamic performance and aerothermodynamic environment for an aerobraking orbital transfer vehicle would be of major significance for the design and development of future flight systems.
